Windows FM Radio support in v5.

[canadianeh]

Hi All,

I'm trying to implement this using the AVerMedia USB Polaris Analog Capture device (I assume the same USB dongle the original tester used).  I can get the device to enumerate with ffmpeg, along with channel changing in ffmeg GUI and able to play the stream in VLC.

The python script worked beautifully, NextPVR was able to find the extra tuner and add in the channels contained in the XML.  

However, when I go to the EPG and choose any radio station from the list, I get "starting device, please wait" and then "Streaming failed. Transcoder exited".  

I am testing this using the web UI and NextPVR 5.2.2.211017.  I can upload logs somewhere, if that would be helpful?


Thanks!

Great, sounds like you are close. Did you follow these steps for installing python https://github.com/sub3/NextPVR/wiki/install-python There are often issues of not installing python properly.

Actually looking at the source (it has been a long time), python is only used for creating the xml file

Before trying it as an extra, find a local frequency from the xml file and make sure it works

AnalogRadio.bat "frequency" | "C:\Program Files\NextPVR\Other\ffplay" -i pipe:

If you get errors remove the -v panic from the bat file and see if something shows up.

I somehow missed the wiki page.  I think this might be the problem?  It keeps installing the modules in the user folders.  Do you know of a way to force it not to do this in Windows?

Don't worry about that, since as I just noted that you only need the user role it isn't used at runtime. Check my last post.

Awesome.  So I ran the batch file as requested, here is the output:

The frequency will be 92500000

If that doesn't work you need to remove -v panic from the command line in the batch file to see more errors

I'm thinking the python script didn't run correctly.  I'm going to try deleting the batch file and XML, and then re-run again to see if that helps.

Seems you missed a step https://forums.nextpvr.com/showthread.ph...#pid539855 to change the tuning names to your Polaris device.

Yes - sorry about that! Running the batch file now pops open the Pipe: window and I can see it act like it is streaming data, however there is no sound.  Also launching from within NextPVR's TV guide in the web client, it acts like it is streaming, but no sound is present.  Trying it with the NextPVR windows client, it freezes the window and does nothing.
